Maintenance of Centrifugal Scraper Film Evaporator

1) The lubricating oil of the reducer is 40# engine oil, and the amount of refueling should be within the indicated height. Too much oil will cause stirring and heat generation, and too little oil will destroy the oil film of the eccentric body shaft pump and cause heat to rise, resulting in temperature rise. When starting to use, replace the secondary lubricating oil within 1 month, and then replace the lubricating oil once every 3-4 months.

2) After opening the low head, unscrew the bolt at the bottom of the U-shaped groove of the rotor, check the scraper and replace the scraper every four months.

3) Open the bottom bearing every two months, check the wear of the bottom bearing, and replace the bottom bearing if necessary.

4) According to the nature of the material, the inner cylinder should be soaked and cleaned with warm water or solvent regularly.

5) Add sealing liquid to the mechanical seal cavity once a month, and the sealing liquid is 20# mechanical oil.
